[n-Vi] posilble to bi-amp?

Nope!

The centre & rear amps aren't assignable, and only come into play when digital sources are fed into the unit.

Mike is right.

But if you wanted passive bi-amping then this should be possible AFAICT. Just have the appropriate 5-pin to 2 x XLR (or whatever) cable made up and pass through a pair of (say) 250.2's and the job's done.

Assuming that is that your speakers can handle full range inputs and are not expecting some upstream crossover. And also providing the output impedence of the n-Vi will allow this. Naim pre-amps do - I've done that with an 82 straight into 4 x 135 driving EPOS's.

I can't vouch for the n-Vi impedence; you'll need to talk to Salisbury.

It's just the nice thing that it is a one box solution. And if you gone put extra boxes to it you get the same "problem" ( less place for boxes )

I thought 5 amps integraded. And if you gone play trew 5 channel setup. Isn't it posible ? ( what means: assignable )

Assignable: possible to choose exactly what signal you want to go through each amplifier module, instead of the channel (left, centre, right surr left, surr right) that it was designed for.

Anyway, Naim don't consider bi-amping appropriate unless doing so using active crossovers and passive speakers, so it was pretty unlikely they'd design that capability into the n-Vi
